Description

Technical Field

[0001] The present invention belongs to the technical field of pressure pipeline pressure detection equipment, and in particular, relates to a pipeline pressure detection device and a use method thereof. Background Art

[0002] Special equipment refers to equipment with high risk, so when producing such equipment, the production quality of such equipment needs to be strictly guaranteed. After the pressure pipeline of special equipment is produced, the pressure pipeline needs to be tested for pressure to ensure safety during use; and the pipeline pressure testing device is widely used in the fields of petroleum, chemical industry, natural gas, water, etc. By using this device to test the pipeline pressure, it can be ensured that the pipeline meets the relevant standards and specifications during the design and manufacturing process, reduce the risk of safety accidents during the use of the pipeline, and protect the lives and property of the people.

[0003] After searching, Chinese patent No. CN217059629U discloses a special equipment pressure pipeline pressure detection device, which relates to the technical field of pressure pipeline pressure detection equipment, including a detection device body, a support plate in the detection device body, a support member at the bottom of the support plate, a through hole on the support plate, a first threaded rod in the through hole, a ring at the lower end of the first threaded rod, a first clamp on the first threaded rod, a second clamp on the first clamp, a pressure detection device on the support plate, and a driving device on the upper side of the pressure detection device. The first threaded rod is inserted into the through hole for fixing, and then the pipeline is placed in the first clamp, and then the second clamp and the first clamp are clamped and fixed to the pipeline, so that the detection device can fix pressure pipelines of different lengths, thereby improving the stability of the pressure pipeline, and after the fixing is completed, the driving device can control the pressure detection device to perform pressure detection on the pipeline, and the pipeline can remain stable and motionless, so that the detection result is more accurate.
